GLideN64: Toukon Road 1 & 2, Last Legion UX: HLE implementation

Hello,

As you know, there are several games, which does not work in HLE mode. Some games have major glitches, some does not work at all. These games use custom microcodes. We have no information about these microcodes and it is very unlikely that such information will appear someday. We still can run any game in LLE, but HLE is obviously faster. Thus, attempts to decode custom microcodes and improve quality of HLE emulation continue. The only way to do it is to analyse assembler code and try to understand what it does. It is very hard task, which only few people in the world can do (not me), so progress is slow.

olivieryuyu, the main beta tester of Glide64 and GLideN64, decided to take decoding task and already achieved great results. Recently he decoded microcode, which is used by Toukon Road 1 & 2 and Last Legion UX games. You can read details about it on wiki page:

https://github.com/gonetz/GLideN64/wiki/T3DUX-ucode

Cite: "Last Legion UX, Shin Nihon Pro Wrestling Toukon Road - Brave Spirits and Shin Nihon Pro Wrestling Toukon Road 2 - The Next Generation uses a undocumented Nintendo ucode called T3DUX.
Shin Nihon Pro Wrestling Toukon Road - Brave Spirits uses the version 0.83 and the two other games 0.85.
It is an evolution of the turbo3d microcode which is used only by one game in its original format, Dark Rift.
The major change in T3DUX compared to turbo3d is what we can called a colors & texture coordinates state."

From my side, I wrote HLE implementation of that ucode. Screen shots:
